Gravity's Surprising Capabilities: From Eliminating Dark Energy to Creating Light

Physicists have explored alternative theories to explain gravity without the need for dark energy, including non-metric gravity, which describes gravity as a deformation of spacetime geometry but differs in the way matter interacts and changes it. Researchers have found that non-metric gravity agrees with astronomical data even better than general relativity and does not require the presence of dark energy. However, further experiments are needed to confirm its viability as an alternative to Einstein's theory.
